PURPOSE: An automatic machining tool for drilling reference bores on a printed circuit board is provided to drill high quality standard bores by attaching a PCB on offset positions and forming a cover layer on the PCB. CONSTITUTION: An automatic machining tool for drilling reference bores on a printed circuit board comprises a workpiece carrier(1), one or more drilling stations, PCBs(3,3'), and a removing device. The workpiece carrier stores the PCBs. One or more drilling stations machine the PCBs. Each PCB is successively attached to the workpiece carrier. The removing device removes the PCBs from the workpiece carrier. |
